HANDLE FOR CROSSCUT-SAWS.

SPECIFICATION forming part of Letters Patent No. 327,776, dated October6, 1885.

Application filed May 15, 1885.

To all whom, it may concern:

Be it known that I, CHRISTOPHER ElSEN- HARDT, a citizen of the UnitedStates, and a resident of Philadelphia, Pennsylvania, have inventedcertain Improvements in Handles for Crosscnt-Saws, of which thefollowing is a specification.

My invention relates to certain improvements in crosscut-saw handles,the object of the'invention being to produce a handle capable ofeilicient use in different positions with respect to the saw-blade, asmore particularly hereinafter set forth.

In the accompanying drawings, Figurel is a side view of my improvedhandle attached to the rear end of a saw-blade, a portion of the latterbeing shown. Fig. 2 is a perspective View of the handle attached to therear end of a saw-blade, but at right angles to the latter, as when thesaw is to be used in cutting down trees. Fig. 3 is a side View of myhandle attached to one end of a saw-blade, at the top thereof, as wherethe work to be done is that of sawing fallen trees, and Fig. 4 is aperspective View of the handle.

Referring to Figure 1, Ais the handle, and B the saw-blade, the twobeing connected by a well-known clamp, D, consisting in the pres entinstance of two metal plates or washers, c 9, between which the handleis grasped, and a longitudinally slotted bolt, (Z, passing through thesaid grasping-washers and handle, and having at its outer end eyes,through which and through an aperture in that part of the saw-bladewhich is received within the slot of the bolt passes a pin, (2. Theother end of said bolt d has a screw-thread for the reception of thethumb-nut, the tightening of which against the washer g secures bladeand 0 handle rigidly together.

For the slotted bolt (2 a bolt having at its outer end a hook to passthrough the eye in the blade may be substituted.

\Vasher 0, against which the rear or top edge of the saw-blade bears, isprovided, as usual, with two central grooves at right angles to eachother, the blade finding its bearing in one or other of these grooves,accord- Serial No. 165,588. (No model.)

ing to the position in which the handle is at tached to the blade.

The handle is formed as follows: It has a straight portion, 0, by whichit is attached to the saw-blade, two horns or projections, 7b '23, eachof a size and shape adapting it to beconveniently grasped by the usershand, a bent 5 5 or curvilinear portion extending from the base of oneto that of the other of said horns or projections and of a character andlength affording two several hand-holds, b b, and a piece,

0, connecting horn or projection iwith straight side 0. These partssurround a central aperture, f, ofa shape and size allowing for thereception of the inner end of screw-bolt (Z and its thumb-nut, and alsofor the passage of the users hand for the purpose of grasping the part aof the handle without coming into contact with said bolt or nut.

If this handle be attached to the saw in either the position shown inFig. l or that shown in Fig. 2, the operator may conveniently operatcthe saw, if the work be sufliciently light, by grasping section b ofpart a of the handle with one hand, while, if the work be heavier, hemay also grasp the horn or projection IL with his other hand. 7 5

If the handle be attached to the saw as shown in Fig. 3, the operatormay work the saw conveniently by grasping the section Z) of part a ofthe handle with one hand and the horn or projection t' with the other.

It will be noticed that the horns or projections ht are at an angle toeach other, projection It being practically on a line with side 0 andprojection t with side c of the handle, so that when the handle isattached to the end of the blade the projection h and when it isattached to the top of the blade the projection 1' is in the bestposition to serve as a handhold.

It will also be noticed that the shape of the handle and the relativepositions of the horns It and 1 and the intervening bent or curvilinearpart a of the handle to each other and to that part, c, of the handle bywhich it is secured to the blade are such that whatever the 5 positionof the handle with respect to the blade one of the operators hands, whenboth are used, will be a little to the rearward of the othera conditionmore advantageous and less tiresome than where the hands are closetogether or in line with each other.

It will also be noticed that the relation of the bent or curvilinearpart (6 of the handle to the straight side is such that whether theposition of the handle be that of Fig. 1 or that of Fig. 2 the operatorsgrasp upon said bent or curvilinear portion a'is at such a point thatthe thrust upon the blade is practically upon a plane with the line oftravel of the blade. This, when the handle is in the position ofFig; 2,prevents the tendency to buckle existing when the handle is of suchconstruction line.

that the thrust is from above or below that In the present instance thecurvilinear portion a or grip of the handle is shown as of such a lengthand curvature as to present two distinct hand holds, 1) b, substantiallyat right angles to each other; but I wish it to be understood that I donot desire to confine myself to the precise form and proportions shown,as it will be evident that they may be changed without departing from myinvention so long as the grip a extends above and in rear of the openingf of the handle, so as to present a convenient hand-hold for theoperator, whether the handle be attached to the end or top of the blade.

Ielaim as my invention- 1. A saw-handle having a portion, 0, whereby itmay be attached either to the end or top of a saw-blade, a hand-hold, f,a grip portion, a, and a projection, 1', said grip portion extendingabove and in rear of the hand-hold and permitting the convenient graspof the handle whether the latter is attached to the end or top of theblade, and said projection i providing an additional hand-hold above thegrip a when the handle is attached to the top of the blade, allsubstantially as specified.

2. Asaw handle having a portion, 0, whereby it may be attached either tothe end or top of the saw-blade, an opening, f, a grip portion, a,extending above and in rear of said opening, and projections h and t atthe extremities of said grip portion a, all substantially as and for thepurpose set forth.

3. Asaw-handle having a portion, 0, whereby it may be attached either tothe end or top of a sawblad, and having handholds Z I), substantially atright angles to each other, and an opening. f, between said hand-holdsand the portion 0, all substantially as and for the purposes set forth.

4. A saw-handlehavinga portion, 0, whereby it may be attached either tothe end or top of a saw-blade, two hand-holds, I) b, substantially atright angles to each other, an opening, f, between said handholds andthe portion 0, and projections hi at the extremities of said hand-holdsb b, all substantially as set forth. a

In testimony whereof have signed my name to this specification in thepresence of two subscribing Witnesses.
